How do you build Europe's first sovereign high-performance processor from scratch? What does it take to challenge Intel and AMD with just 200 engineers and €150 million?

In this comprehensive episode of Opening Voices, I sit down with Philippe Notton (CEO) and Craig Prunty (VP) from SiPearl to explore Europe's most ambitious semiconductor project:

🔹 How 200 engineers across 5 R&D sites design a 60 billion gate processor

🔹 Why ARM is becoming the new battlefield for server processors

🔹 The €20 million data center built to emulate Europe's most complex chip

🔹 How hyperscalers like Amazon and Google are driving the custom silicon revolution

🔹 Why AI inference on CPUs can be 70x more energy efficient than GPUs

🔹 The chiplet revolution and Europe's opportunity in post-Moore's Law era

We dive deep into the technical challenges, market dynamics, and geopolitical implications of building sovereign computing infrastructure in Europe.

Why are CPUs making a comeback in the age of AI? And how can Europe build a sovereign compute infrastructure in a world dominated by American and Asian tech giants?

In this final episode of Opening Voices with the SiPearl team, I sit down with Philippe Notton (CEO) and Craig Prunty (VP) to explore the future of processor design and its impact on AI, sovereignty, and Europe’s industrial strength.

We discuss:

🔹 Why CPUs can outperform GPUs in inference workloads

🔹 How SiPearl’s chip design drastically reduces energy consumption

🔹 The growing importance of chiplet architectures for modular compute

🔹 Why Europe needs its own electronic design cloud infrastructure

🔹 How to reclaim industrial skills and build a sovereign value chain

🔹 The difference between SiPearl and ASML in the semiconductor ecosystem

🔹 Why sovereignty isn't about isolation—but about control and resilience

Why are tech giants like Apple, Amazon, and Google building their own processors—and what does it mean for Europe?

In this new episode of Opening Voices, I sit down with Craig Prunty, VP at SiPearl, to explore how processor design is becoming a strategic lever for performance, sovereignty, and efficiency.

We discuss:

🔹 Why ARM is taking over the server market

🔹 The real reasons hyperscalers are going boutique in chip design

🔹 What makes European players like SiPearl competitive—despite limited funding

🔹 The opportunities for Europe to scale its processor ambitions with partners like TSMC

How can Europe bridge the semiconductor gap with the US and Asia—before it’s too late?

In this third part of my conversation with Philippe Notton, CEO of SiPearl, we dig into the real-world consequences of Europe's chip dependency and the massive effort required to catch up.

🔹 Why Europe is at least two decades behind the US in chip design
🔹 How geopolitical shocks like COVID and Ukraine revealed our supply chain fragility
🔹 What it takes to rebuild a complete, sovereign semiconductor value chain
🔹 Why timing and political will are critical to success

How can Europe reignite its innovation engine and avoid falling behind in the global tech race? What lessons can Europe learn from the US DARPA model?

In this pilot episode of Opening Voices, I speak with André Loesekrug-Pietri, Chairman of JEDI (Joint European Disruptive Initiative), often called the 'European ARPA,' to explore:

🔹 The origins and mission of JEDI in driving disruptive innovation in Europe;

🔹 How JEDI's approach to funding advanced research differs from traditional European methods;

🔹 The key elements of the DARPA model that Europe can emulate, including a tolerance for failure and a focus on strategic impact;

🔹 Why Europe needs a sense of urgency and a willingness to take risks to compete with the US and China.
